In [4] has been proved the bijectivity of a natural mapping Φ from words on a totally ordered alphabet onto multisets of primitive necklaces (circular words) on this alphabet. This mapping has many enumerative applications; among them, the fact that the number of permutations in a given conjugation class and with a given descent set is equal to the scalar product of two representations naturall...

We present a novel approach towards a multimodal analysis of natural speech and handwriting input for entering mathematical expressions into a computer. It utilizes an integrated, multilevel probabilistic architecture with a joint semantic and two distinct syntactic models describing speech and script properties, respectively. Compared to classical multistage solutions our single-stage strategy...

There has been substantial recent interest in captured design expertise expressed as design patterns. Prevalent descriptions of these design patterns suffer from two demerits. Firstly, they capture specific instances of pattern deployment, rather than the essential pattern itself, thus the spirit of the pattern is often lost in the superfluous details of the specific instances described. Second...

{cpaz, renata, kon}@ime.usp.br Abstract. Looking for information in long videos can be a time-consuming experience. The ONAIR system was developed in order to allow the users to find the information they want through queries in written natural language. We implemented the vector space model for information retrieval and used ontologies to improve the retrieval. In this paper we describe the sys...

introduction urban landscape is experiencing rapid changes which put all urban domains under pressures. these processes revolutionize urban landscape into spaces without ecologic values. the sustainability of green patches and corridors has been scathed by lack of ecological approaches in planning and design. therefore, urban green spaces structures and functions have been damaged. green spaces...

medical environments such as hospital waiting rooms can affect a client’s anxiety level as wellas psychological and physiological responses to his or her situation. the aim of this research was to evaluatethe use of environmental design, specifically the design which incorporates elements of nature, in clinics andhospitals to decrease anxiety, blood pressure and pulse rates of waiting clients. ...

A design pattern realization consists of a cluster of classes that work together to solve a particular problem using a well known, named solution. Developers may build systems out of several pattern realizations, and these pattern realizations may be interconnected, or, in other words, coupled. Coupled pattern realizations may represent a reasonable solution to software design problems, however...

Much of the detailed knowledge required to implement good Software Connguration Management systems has not been adequately cataloged and documented. The Design Pattern methodology provides a means to help rectify this deeciency. Based on the authors' experience in implementing Software Connguration Management tools, a selection of basic techniques for Software Connguration Management are presen...

Referential qualities are qualities of an entity taken with reference to another entity. For example the vulnerability of a coast to sea level rise. In contrast to most non-relational qualities which only depend on their host, referential qualities require a referent additional to their host, i.e. a quality Q of an entity X taken with reference to another entity R. These qualities occur frequen...
